- Internals: Cylinder barrel adopts GUOYUE EU/US metallurgical standard CD250 structure. Barrel material: 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm. Heads, base, trunnions, and pistons are exclusively made of 45# steel; no cast iron or cast steel components are used.
- Buffering: Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
- Welding: 100% ultrasonic impact treatment applied to all pressure-bearing and load-critical welds. This eliminates weld stress (removal rate ≥90%) and significantly enhances weld fatigue strength.
- Sealing: All cylinders exclusively use premium imported seals from Japan , Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
- Testing & Certification: Factory testing strictly complies with GB/T15622-2005 "Hydraulic Fluid Power - Test Methods for Cylinders" and internal premium standard Q/GAKY014-2023. Includes provision of factory test reports and product qualification certificates.
- Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period.
- Maximized Reach: 5-stage design achieves 8m+ extension while collapsing to 30% length.
- High Load Stability: Synchronized stage movement ensures ≤1° tilt under 50-ton loads.
- Space Optimization: Compact retracted size fits crane boom cavities.
- Corrosion Resistance: Hard-chromed rods + epoxy coating withstand road salt/moisture.
- Precision Control: Integrated pilot-operated check valves prevent drift during positioning.
- Utility Cranes: Telecom tower erection, transformer handling.
- Log Loaders: Timber stacking at roadside.
- Recovery Trucks: Wrecked vehicle lifting.
- Construction: Precast concrete placement.
- Mining Service: Drill rod replacement in pit.
- Disaster Response: Debris clearing in confined zones.
